[Milsurplus] TCK-4

[Bruce Gentry]

I spent 33 years in the elevator business, and heartily agree a good MG 
set definately adds a nice ambiance. A big older Otis or Westinghouse 
that has sleeve beairings and runs at 1200 rpm is a very pleasent sound 
indeed. The newer and more compact ones, especially those that run at 
3600 RPM can be annoying screamers. Many people today will find any 
motor noises unacceptable and strive for near or total silence, but a 
properly serviced dynamotor in a BC-348 or ARC-5 receiver adds a lot to 
the experience of using them.  For older transmitters, the stiffness of 
an MG set power source was often the deciding factor in frequency 
stability and good modulation.
